My kiwi plant gets nice blossoms, but when the fruit starts to grow, it either falls off the plant before it gets to the size of a pea or something is eating it. What would you suggest I do?
It sounds like the flowers are not being properly pollinated. Kiwi need both a male and female plant for proper pollination. If you only have a female plant, the fruit will fall as you describe.
If you have a male and female kiwi plant, and this is still happening, you may be having issues with pollinators being able to get at the flowers. These articles will help you with that:

I bought a single plant and was told it would be all right with one, as it was meant to be self fertile (named Jenny by strain). I live in Tayside in Scotland.
Yes, there are one or two varieties that are self fertile. They are harder to find, but if yours is one of these varieties, then you only need one plant. The Jenny variety is listed as being a self fertile variety.
How do you recognize the differences between a male and female kiwi plant?
You can only tell them apart once they flower. The female flower will have a small ball inside the flower (which is the immature kiwi) while the male flower will not.
My kiwi plants -both male and female- are 5 years old and they have never bloomed or produced fruit. The foliage grows great though. Do they need something else besides compost and fertilizer to produce?
It can take up to 6 years for kiwis to bloom, so they may not be mature enough yet. But, just in case, I would provide them with a bit of phosphorus rich fertilizer to encourage blooming.
How do I tell the female plants from the male plants? I received the plants, but without labels. All the instructions said was to plant the male and female plants within 6 feet of each other. I received four of them and I was planning on giving one set away to a friend but don't want to give away what would turn out to be an incomplete and fruitless gift.
The female flower will have a tiny fruit inside the blossom. Males will not. Until they flower, you cannot tell the sex.
I would like to do a kiwi farm in Moldova. We have good fertile soil with good water for irrigation. We also have a very cold winter with an average temperature about -8 C and a long, sunny summer with an average temperature about 25 C. I would appreciate it if you could advise me regarding this matter.
You will not be able to do tropical kiwi, but you can do hardy kiwi. They are smaller, but taste just as good. Here is an article on them:
